1. To measure the liquid permeability of a sample, a core 2 cm in diameter and 5 cm
long was used. Brine was flowed through the sample at a flow rate of 1 cm3/sec. If
the pressure drop was measured to be 5 x 107 dynes

Chapter 3 Integral Relations for a Control Volume
3.1 Discuss Newtons second law (the linear momentum relation) in these three forms:
F = ma F = d (mV) dt F = d V d dt system
Solution: These questions are just to get the students thinking about the basi

Chapter 5 Dimensional Analysis and Similarity
5.1 For axial flow through a circular tube, the Reynolds number for transition to turbulence is approximately 2300 [see Eq. (6.2)], based upon the diameter and average velocity. If d = 5 cm and the fluid is ke

Chapter 1 Introduction
1.1 A gas at 20C may be rarefied if it contains less than 1012 molecules per mm3. If Avogadros number is 6.023E23 molecules per mole, what air pressure does this represent? Solution: The mass of one molecule of air may be computed a

Chapter 6 Viscous Flow in Ducts
P6.1
An engineer claims that flow of SAE 30W oil, at 20C, through a 5-cm-diameter smooth
pipe at 1 million N/h, is laminar. Do you agree? A million newtons is a lot, so this sounds like
an awfully high flow rate.
Solution:

Chapter 7 Flow Past Immersed Bodies
P7.1
An ideal gas, at 20C and 1 atm, flows at 12 m/s past a thin flat plate. At a
position 60 cm downstream of the leading edge, the boundary layer thickness is 5 mm.
Which of the 13 gases in Table A.4 is this likely to

1. (Continuation of problem 4 in HW#4) An oil reservoir consists of a sequence of
inter-bedded sands and shaly-sands. The capillary pressure curves (measured
with crude oil and brine) for the sands and the shaly-sands are gi
